STRIPPER-HARVESTER.

To all whom 'it may concern:

Be it known that l, CHARLES A. ANDER- rcsiding at Chicago, in tlic county of 'Cook and State of Illinois, have invented certain new and useful Improvements in Stripper- Harvesters, of which the following is a specification, reference being had to the accom- .pan ing drawings, forming a part thereof.

. A y invention relates to that class of harvesting machines commonly called stripper hrarvesters,lin the operation of which the heads of the rain are stripped from the stalks and elevator? to athrcshing, separating and cleaning mechanism and the grain delivered to a receiving receptacle. y

J The objectsofthe invention are to improve the lconstruction of the frame structure in amanner to renderit adjustable when required and rigid and strong `while in o eration ,i to provide a two-part or flexible s aft upoirwhicli the stripping cylinder is m0nted;to rovide an improved journal supportl for t je threshing cylinder; to an imlproved ,if construction of the threshing cy inder whereby the-shaft upon which it is mountedjisarranged in roper alinement, and to reducethexeost o? the machine by means 'of its simplified construction. These objects are attained by tlie mechanism illustrated by the drawings and described in the specification.

Referring to the drawings, in which like referencey numerals designate the same parts .throughout the several views-Figure l is aside elevationfof a harvester embodying my improvements ,i Fig. 2 isa detail dravmg,p artly in's'ection, and designed to illustrate the 'construction of the threshing cylinder; Fig. 3 is a detaildrawing oi a cani Washer forming/a part ofthe alining mechanism -of. the shaft upon which the threshing cylinderf-is mounted; Fig. 4 is a topplan view ofthe machine showing the construction of the main frame aiid the manner of mounting the stripping` and threshing cylinders; Fig. 5 is a sectional end View of the stripping cylinder designed to illustrate the manner ofadjusting the stripper bar relative to the rotatable cylinder; Fig. 6 is a detail drawing, partly in section, and designed to illustrate the construction ol thc flexible shaft upon which the stripping cylinder is mounted; Fig. 7 is an enlarged l Specification of Letters Patent.

The draft, or main wheel frame, consists, in part, of the frame-bars 3 and 1l, located upon opposite sides of the main wheel 5 that is joui'iialcd upon an axle 6. The l'rninebars 3 and 4 are secured at their rear ends to parts 7 and 8 'that are supported. on tli I :ixle 6 and extending forward iii converging lines, are connected -at their forward ends to a spacing bracket 9, in which is secured a vertical stein 10 forming part of a poleI truck 11. Below the wheel frame, and supported upon the axle, is a tilting bed :frame having outside members 12A and 13 and an intermediate member 14 extending in the direction oi the draft of the machine and 'iront and rear cross sills 15 and 16 secured' thereto, and n.

diagonal member `17 extending l'ioin the gramward member 13 in proximity to thc axle and joined to the forward end ol the stubblewaid member 12. A sector-ruoli 1S, concentric with the axle 6, is secured at its` lower end to the forward end of the frame member 12 and has its upper end connected with the. rear end thereof' by means ol' n.

brace. rod 19.

A plato member QO'is secured to the converging wheel frame bars and forms a guide for the tilting scctor-rack'and also a support for a worm 21, operatively connected with thel sector-rack and havinga vertical crank .shaft 22 whereby it.- may be operated in a mannerto tilt the machiiicas desired. Upon the tilting frame is arranged a-vcitical frame. having upwardly converging hars 23 and 24 that are secured at their lower ends to the bed frame members and at their upper ends to an ear 25 forming part o1' a casting 2t),

from sagging and,` b means of t able connection oft e rod- 28 with the bed. frame, the parts may be adjusted as desired direction.

A brace rodA 29 is connected at'its u .per`

end with the casting 26, and extend-ing t iegonally downward, forward and grainward, has its opposite end connected tothe'fraine member of the tiltingbed frame, whereby the granward endl of said .frame is Ilnevented e adju stfor the purpose of arranging the operative parte in pro `r. relation with each other.

TheI thres ing cylinder consists of a supporting shaft 30; upon which is mounted a series of angular plates 31', having axial o en- ,ings adapted to receive the shaft, the 'p ates b'ing spacedapart by means of short thini.

bles 32, and 33.*represent threaded clamping members that, in combination with Ia sleeve 34 and washer 35, o erate to draw the plates and thimbles Closey together in operative` relation and to p'revent distortion. of the shaft, and for the purpose of maintainingA it in proper alinement when the parts are drawn together, there is provided an equalizing cam washer 36 intermediate the sleeve 34 :i nd

the adjacent plate that' is adapted' to roel; relative to the axis of the shaft upon its oppositely-v arranged bearing points 37 and 3S, as shown in Fig. 3, in la manner to eqnaiize the strain of the nuts and revent an)Y dis` tortion of the shaft. The i yaft is j-ournaled in a sleeve 39 that' is rovided at voppo.-.ite ends thereof with rol er bearingsm, the sleeve being mounted at it's rainward end in a bracket41 secured to the support ing frame, and its stubbleward end is received by an openin in the casting 26 and 42 designates radia y arranged set screws lthat are received by the casting 26 in a manner to cause the inner ends to contact with said sleeve whereby it may be adjusted relative to said casting as desired to maintain the cylinder in proper operative relation with its associated parts.

The strippin vcylinder consists ot' .the usual shearing blades 43 secured to the. outer ends of spiders 44' that are secured to a flexible driving shaft 45, having its outer lend journaledin-bcarings secured to the tilting frame of the machine. In the construction of machines of the type indicated the practice has been toA provide. a continuous oncpiece shaft supportedin bearings at its o p posite ends, upon which the spiders and shearing blades have been mounted, with theresult that when in operation there would he.

bporting shaft 'that is jointe portion inn manner't-o allow it to conform 'more or less flexing of the shaftbetween its aggravated in machines having a wide cut.

To remedy the defcctthcre is `rovided asuiatits midi e i'tself to any disarrangement of the associated parts of the stripping mechanism. As illustrated in Fig. 6, the shaft consistsof two parts, having their inner ends reduced in diameter and loosely received by axial openings at opposite ends ofA a bearing inember 46, to which they are connected b v means of'pins 47.I The .bearingr member is journaled in a sup orting bracket 4S, that is secured to'the anti-friction rollers formingr )art of the jonrnal bearing. A shearingr lmr 5l), having strippingr lingers 5l secured thereto, is mounted in )ro )er operative relation with the shearingl blades of the stripping cylinder by means ol a central sccurinpr bolt. 52 engaging with lthe bar andthe supporting bracket, as illustrated in l-`ig-s. 5 and 7. 53 represents set screws that 'are received by the virackcts and having their inner ends contacting with said har, whereb)v thevinayv be manipulated in n inanner to adjust thc bar bodily and radially toward or from theaxinl lineof the stripping c vlinder for the purpose of niaintainingr the associateil parts ol' the stripping: mechanism in proper operative relation.

. The threshcdgrain is. received ,from the separating'mechanism by the lower end of ed vframe, and 49 represents van elevatinpr chute 54, f roin which it is delivered into a conducting spout 55, which de? liversI it into agrain receiver 56, which is provided with a hinged gate 57 adapted to lie-v controlled in a manner to empty the receiver of its contents in .sacks 'as desired.- The rain recei-ver.is mounted upon the. tilting 'rainc of the machine and'is connected with thc wheel fra-ine. by means of a pair of counterbalaiicing,r springs t'that extend diagonally forward and downward, as shown in Fig.

13, and operate to assist the operator incontrollingr the position of the two frames relative to cach other. The tension of the spring-slimy be adjusted by means of nuts 59.
